Calculating the Solar Heat Gain of Window Frames
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1999)It is not practical to measure the solar heat gain of a window frame. It is more practical to do so by calculation. Typically, the frame solar heat gain is a small component of the total or is small in absolute terms so ... -
A Correlation to Quantify Convective Heat Transfer Between Vertical Window Glazings
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)Several correlations have been used in recent years for the purpose of calculating convective, centre-glass heat transfer rates across gas-filled interpane window cavities. These correlations are examined and their background ... -
Overview of a Project to Determine the Surface Temperatures of Insulated Glazing Units: Thermographic Measurement and Two-Dimensional Simulation
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)A collaborative research project was undertaken to generate surface temperature profiles for the indoor side of seven different double and triple-glazed insulated glazing units exposed to the ASHRAE winter design condition. ... -
A study of insulated glazing unit surface temperature profiles using two-dimensional computer simulation
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)This paper describes one part of a collaborative research project, including both measurement and simulation studies, aimed at determining the surface temperature of a set of insulated glazing units (IGUs). In this study ... -
Summary and comparison of methods to calculate solar heat gain
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-08)Methods used to calculate the solar gain of windows (including center-glass, edge-glass, and frame) are examined and compared Particular attention is devoted to the public-domain computer programs VISION3 and WINDOW 4.1. ... -
Thermal Resistance of a Window with an Enclosed Venetian Blind: A Simplified Model
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2008)Solar gain has a strong influence on building energy consumption and peak cooling load. Venetian blinds are routinely used to control solar gain. Software based on 1-D models is available to accurately predict the thermal ... -
Thermal Resistance of a Window with an Enclosed Venetian Blind: Guarded Heater Plate Measurements
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2006)Window solar gain is known to have a strong influence on building energy consumption and peak cooling load. Venetian blinds are routinely used to control solar gain. Software based on one-dimensional models is available ... -
A two-dimensional numerical model for glazing system thermal analysis
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-08)A simple two-dimensional (2-D) numerical control volume formulation is presented that can be used to model heat transfer through a vertical insulated glazing unit. This model accounts for natural convection of the fill gas ...
